ieee8021AsPortStatRxSyncReceiptTimeouts

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortStatRxSyncReceiptTimeouts

OID (numeric): 1.3.111.2.802.1.1.20.1.6.1.8

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A counter that increments every time sync receipt timeout occurs, denoted by entering the AGED state of the PortAnnounceInformation state machine (see 10.3.11 and Figure 10-13), with the condition (currentTime greater or equual to announceReceiptTimeoutTime) TRUE

What is ieee8021AsPortStatRxSyncReceiptTimeouts?

A counter of how many times this port has entered sync receipt timeout, i.e. gone the configured number of sync intervals without receiving time-sync info. Repeated increments indicate an unstable upstream sync source on this port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.8
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatRxSyncReceiptTimeouts

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.8.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatRxSyncReceiptTimeouts.1
